What is carbon monoxide and
-, why should you be concerned?
Carbon monoxide is a dangerous, poisonous gas. It is
often
referred to as the
Silent Killer
because it has
no odor or
taste and it can’t be seen. The presence of
carbon
monoxide inhibits the blood’s capacity to
transport oxygen throughout the body, which can
eventually lead to br;tin damage.
In any enclosed space (home, office, recreational
vehicle or boat) even a small accumulation of carbon
monoxide can be dangerous.

What
are
the potential sources
y of carbon monoxide?
Although many products of combustion can cause
discomfort and adverse health effects, it is carbon
monoxide (CO) that presents the greatest threat
to life.
CO is produced by the incomplete combustion of fuels
such as natural gas, propane, heating oil,‘kerosene, coal,
charcoal, gasoline or wood. The incomplete combustion
of fuel can OC~LUin any device that depends on burning
for energy or heat such as furnaces, boilers, room heaters,
hot water heaters, stoves or grills and in any gasoline-
powered vehicle or engine (e.g., generator set or lawn--
mower). Tobacco smoke also adds CO to the air
’
you
breathe.
When properly installed and maintained, your natural
gas &nace and hot water hater do not pollute your
air space with carbon monoxide. Natural gas is known
as a “clean burning” heI because under correct operating
conditions the combustion products are water vapour
and carbon dioxide, which are not toxic. (Carbon dioxide
(CO*) is also present in the air we exhale and is necessary
for piant Me.) The products of combustion are vented
from furnaces and water heaters to the outside by means
of a flue duct or chimney.

Correct operation of fuel-burning equipment requires two
key
conditions. There must be:
l
An adequate supply of air for complete combustion
l
Proper venting of the products of combustion from
the furnace through the chimney, vent or duct to
the outside

What are the possible symptoms of
carbon
monoxide poisoning?
Carbon monoxide (CO) is odorless, colorless, tasteless
and very toxic. When inhaled, it produces an effect
known as chemical asphyxiation. Injury is due to the
combining of CO with the available hemoglobin in the
blood, which lowers the oxygen-carrying capacity of
the blood. In the presence of carbon monoxide, the
body is quickly &cted by oxygen starvation.
The following symptoms are related to carbon
monoxide poisoning and should be discussed with all
members of the household so that you know what to
look for:
Extreme Exposure (A-C)
Unconsciousness, convulsions, cardiorespiratory
failure, death
Medium Exposure (D-G)
Severe throbbing headache, drowsiness, confusion,
vomiting, fast heart rate
MIild Exposure (H-J)
Slight headache, nausea, fatigue
(often described as “flu-like” symptoms)
Young children and household pets may be the first
affected. Exposure during sleep is particularly danger-
ous because the victim usually does not awaken.
The amount of carbon monoxide in the air is measured
as ppm (parts per million). The graph on the next page
shows the important relationship between carbon
monoxide in the air, exposure time and health effects.

Where should you install the detector?
Since carbon monoxide moves freely in the air,
the suggested location is in or as near as possible to
sleeping areas of the home. The human body is
most vulnerable to the effects of carbon monoxide
during sleeping hours. For maximum protection, a
carbon monoxide detector should be located outside
primary sleeping areas or on each level of your home.
In the figure below are suggested locations in the
& home. The electronic sensor detects
Do not place the detector in the following areas:
Where the temperature may drop below
40°F
(44°C)
or exceed lOOoF (37.8”C)
Near paint thinner fkmes or household
cleaning products
Within 5 feet (1.5 m) of open flame appliances such
as furnaces, stoves and fireplaces
In exhaust streams from gas engines, vents, flues
or chimneys
Do
not place
exhaust pipe; in close proximity to an automobile
this will damage the detector.

AHow should you
install the detector?
\‘Your American Sensors Carbon Monoxide Detector is
easy to install to protect you and your family in your
home, cottage, cabin and of&e.
FOR PLUG IN MODELS COSOO, CO910
Simply plug the Carbon Monoxide Detector into
a standard 120 Volt AC wall outlet in your home.
Use unique 90” rotating plug to align vertically in
any outlet.
To provide maximum protection, please allow
one hour for your detector to initialize after placement
in electrical socket.
Do not use detector in an outlet
that is controlled by a wall switch.
If you have a double outlet,
plug the detector into the bottom
outlet so that the top outlet is
available for other use.
To work properly, the detector
must not be blocked by furniture
or draperies.
IMPORTANT: Not suitable as a smoke or fire detector.
This device is not suitable for installation in a hazardous
location, as defined in the national electrical code.

A malfunctioning unit is indicated by a continuing
intermittent single beep and flashing green/red light.
If this occurs, reset the unit. If the unit again beeps
intermittently, do not use this unit. Do not confuse
this single beep sound with the low level carbon

These lines are the normal readout and indicate your
environment does not have a CO problem. If CO is

show the ppms present in increments of 10 starting at 50
(i.e. 50, 60. 70 etc.). Beyond 150 ppm. the unit

5 minutes when first plu gged in. The LED will show
“ERR”
if malfunctioning (see page 16.).
Responding to your Digital LED Display
Your unit is constantly monitoring the air and will
activate a low level warning if low levels of CO are
present. Also, your unit will go into full alarm if
ongoing, dangerous levels of CO are detected. See
Page 24 for the specific times and levels required.
